Red Hat Bugzilla – Bug 125612
works for root only
Last modified: 2007-11-30 17:10:44 EST
Description of problem:
Scanner detection (USB, UMAX Astra 3400) works for root only.
Probably just permissions problem, but its not obvious
what should one do. Adding users to a group (which?)...
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run xsane as non-root user
2. Pop-up window: no device availabe
The problem is apparently in the hotplug tool.
Namely, one can "chmod a+rw /proc/bus/usb/003/002"
after finding the file name with sane-find-scanner,
and xsane works for non-root as well.
However, this must be done after each reboot, see
We ship a hotplug script for SANE: you can power off and on the device
(or unplug/re-insert the USB connector) to achieve what you want.
This needs to be solved properly, and I'm told that udev will
eventually do that.
I think, this is solved better by HAL, as scanners do not identify
themselves easily as "scanner"s. Udev needs strict "rules"
(identifier) to e.g. symlink a device node to /dev/scanner.
also pam_console is good for that...
No, it isn't -- that's what we use right now.
